[Screening of cancerous and precancerous lesions of the oral mucosa in an at-risk population].

Early diagnosis of oral carcinomas allows a limitation of functional consequences of surgical treatment. A prospective study was designed in 270 alcoholic patients. We practiced a clinical examination of the oral cavity by a stomatologist followed by a Toluidin blue test. The clinical examination permitted to detect 1 carcinoma and 23 leukoplakias. The Toluidin blue test revealed one more carcinoma and two leukoplakias more. The early diagnosis of oral carcinomas in alcoholics patients gives them a better survival. The Toluidin blue test could be proposed as an aid to early diagnosis of these carcinomas.

[Alveolar anesthesia].

Tuberosity anesthesia is a loco-regional anesthesia aiming at anesthetizing with a single injection the superoposterior alveolar nerves, by approaching the maxillary tuberosity through a direct anteroexternal pathway. This anesthesia involves an area located behind the pyramidal process of the maxillary bone which includes the molars, gingival buccal mucosa, sinus bone and mucosa. Well-tolerated by the patient, since it is practically a painless procedure, tuberosity anesthesia is the preferred method to perform surgery in the posterior maxillary area. Its administration may be extended without condition to treatment of the upper molars: custy + crown + bridge preparations on vital teeth, pulpectomies, thanks to the rapid onset and efficacy of the anesthesia obtained. The only contraindication involves patients with vascular or hematologic disorders, ruling out procedures where a blood vessel might be injured with a needle. In that case, intraligamentary or transcortical instillation is indicated since para-apical anesthesia is not a valid alternative due to the proximity of the external alveolar artery.

[Behavioral disturbances and psychosomatic manifestations].

The psychological and psychiatrical behaviour troubles and the psychosomatical manifestations are very frequent in dental and oral surgery practice. Their variable expression is sometimes confuse for the practitioner who should quickly find the differential diagnosis with the imperative medical emergency. His attitude must be quiet and kind, still watching over the vital functions and waiting for the more frequent spontaneous favourable evolution.
